Red Liquid Ink In The Air UBA-188M Rollerball

The red uni-ball Air UBA-188M is a liquid ink rollerball pen with a 0.5mm micro tip that varies its line with pressure, sold in a box of 12.

uni-ball says the Air tip releases ink depending on pressure, creating a variable line width, and adjusts to the style of writing by pressure and angle. It says the tip minimises friction for a light and smooth writing experience. uni-ball's page for this model carries the uni Super Ink mark, which uni-ball describes as water, fade and time resistant.

The 0.5mm tip draws a line of about 0.28 to 0.45mm, according to uni-ball, which suits notes, margins and everyday writing in red. Because the line changes with pressure, one pen gives both a lighter and a heavier line. A box of 12 keeps a department stocked in one order.

The other colours in this model are at rollerball pens. The wider uni-ball range is at uni-ball, other pen types at pens, and the rest of the desk at writing supplies.
